Bus Driving: it's not an enjoyable job, and made worse by lack of driver support at MTS
Pros: Work ends when you go home
Cons: Little driver support, slow and dishonest passengers, tight timetables, lots of opportunity to fail (get fired), no opportunity to shine/rise up the ranks (because of union seniority)
I worked as a bus driver for MTS. The pay is not very good, especially after union dues, taxes, and healthcare are taken out. The healthcare is one-size-fits-all, so as a young single person I got a bad deal.
The job is really stressful. The schedules are very tight, so you have to drive fast - which puts you at risk of having accidents (particularly with passengers falling over or whatnot). But what is really going to delay you is the homeless and low-class cheaters and elderly who ride the bus. The best thing to do is probably to just let everyone ride for free when they want to, because otherwise the free-loaders will just argue and delay you. But I did my best to not let the cheaters ride; I just drove even harder. Management could make this job a lot better by giving drivers support in these matters, but they don't. Instead, they encourage the worst riders to ride by issuing heavily discounted passes to "disabled" (and that's in quotes for a reason, because it's largely just a scam) people. But I guess that's part of the business model (think government subsidies).
Starting out, you drive the worst routes at the worst times. Split shifts can easily make your work day 12 hours long. And your seniority isn't going to rise fast, because there are lots of union-supported veterans sitting ahead of you in line with their nice La Jolla routes and inflated pay scales and benefits. So your job won't be getting much better anytime soon.
I quit and moved into a much better compensated and more satisfying field.
